I booted into live CD and I got the options where you can try elementary OS or install it, but every time I choose one of them it turns into a black screen and then after a few second my monitor can't detect a signal from my computer. This never happened to me on other distros just on this one. I have an AMD A6-7400k with r5 graphics and 4gb of ram

Try launching your kernel with nomodeset option, following this instructions:
During the boot process, press and hold SHIFT key. Now you can see the grub menu.
Press e key on first line to edit it.
Go to line with the
quiet splash
sentence. Something like:linux /boot/vmlinuz-4.4.0-57-generic root=UUID=xxxx-xxxx-xxxxx ro quiet splash
.Add the
nomodeset
option betweenro
andquiet splash
. You must see someting like:linux /boot/vmlinuz-4.4.0-57-generic root=UUID=xxxx-xxxx-xxxxx ro nomedeset quiet splash
.Press Ctrl + X to boot the kernel.

A few years later, same problem. My screen was cycling between solid colors when trying to boot into Ubuntu (or Mint) from a live USB stick. The 'quite splash' line didn't have anything similar to the text in this answer. Still, I added ´nomodeset´ just before ´quite splash´, and it worked. Thanks!– pilgixFeb 15 at 23:35
Running Odin [Built on Ubuntu 20.04.3 LTS] in demo mode on an ssd attached by usb-c on a macbook pro: 1× Intel® Core™ i5-6267U CPU @ 2.90GHz
nomodeset did not work for me, but acpi=off works. I saw it in an ubuntu thread. but it notes that this may disable certain critical functions like the fan. Any info on acpi=off appreciated.
Also worth noting: track pad and keyboard do not work, but mouse and keyboard connected by usb do work.
Outside temperature is 95F at hottest spots.. do not hear fan. Will keep checking temp. Otherwise, no issue noted and laser razor fast.
Using a usb dongle that connects by wifi to my left handed orbital trackball with scroll wheel.. and amazingly all of it works perfectly.
